Use saber or conocer.

1-Francisco sabe escribir para revistas

2-Jorge y Anita conocen Miami

3-Yo  conozco una reporta famosa

4-Alma conoce cuántas personas viven en Miami

5-Yo se la dirección del canal de televisión

THANK YOU...

3. There is an error here somewhere because it's either "un reporte" (a report or "una reportera" (a reporter). In any event it is a THING if there is no "personal a" in front of it. Yo conozco un reporte (I am acquainted with a report) OR Yo conozco a una reportera (I am acquainted with a (female) reporter.

4. This is a fact that she knows = sabe (she knows how many people live in Miami rather than she is acquainted with how many people live there.

5. Don't forget the necessary accent mark on "sé" because otherwise it could be confused with the reflexive/indirect-object pronoun: ella se lave OR se lo lava (the car for someone else, etc.)

Sorry, but y ou had a lot of trouble with these five.

Sra

3- YO conozco una reportera famosa .

Is it right?

To determine whether to use "saber" or "conocer" in each sentence, we need to consider the specific context and the meaning intended.

1- Francisco sabe escribir para revistas.
In this sentence, "saber" is used to indicate knowledge or ability. Francisco knows how to write for magazines.

2- Jorge y Anita conocen Miami.
In this sentence, "conocer" is used to express familiarity with a place. Jorge and Anita are familiar with Miami.

3- Yo conozco una reportera famosa.
Here, "conocer" is used to convey personal acquaintance with someone. I know a famous female reporter.

4- Alma conoce cuántas personas viven en Miami.
Again, "conocer" is used to indicate familiarity with a topic. Alma knows how many people live in Miami.

5- Yo sé la dirección del canal de televisión.
In this sentence, "saber" is used to express knowledge or information. I know the address of the television channel.

In summary, "saber" is used when referring to knowledge or ability, while "conocer" is used when talking about familiarity with people, places, or topics.
